BCLSTER.

and exact description, suoli as will enable others skilled in the art to which it appertams to make and use the same,

This invention relates to holsters and the Ono of the objects thereof is to prolike. vide a simple practical bolster having a maximum of lightness, stiffness and strength.

Another object is to provide a bolster of the above type in which the parte so interlock and fit into one another as to reduce the stress up`on the retaining devices holding them together to a minimum.

Other obiects will bc in part obvious and in part pointed out hereinafter.

The invention, accordingly, consists in the features ol' construction, combinations 'of elements and arrangement of )arts which Will be exemplified in thc embodiment thereof hereinafter described and the scope of the ap )lication of which will be indicated in the following claims.

In the accom anying drawings, wherein is shown one of t 1e various possible embodiments of my invention, Figure 1 is an eleva tion thereof, showing its relation to a truck. Fig. 2 is a perspective View of a kingpost. Fig. 3 is a side elevation of an end casting. Fig. 4 is a perspective View of the bolster, certain parts being broken away in order to show the construction more clearly.

Similar reference characters refer to similar partsthroughout the several views of the drawings.

This invention will be most readily grasped if it be borne in mind that a car holster, by reason of its being necessarily subjected to a considerable normal load and to severe wrenching stresses during its use, is generally made of heavy construction,l thus wasting material and diminishing the lightness of the truck. This and other defects arc done away with, without sacrifice of stiffness or stren th, in constructions of the nature of that ereinafter described.

Referring now to the accom anying drawings, there is shown in Fig. 1 a olster mounted upon elliptic springs 1 which rest u on a spring plank 2 suspended as by swingangers 3 from transoms 4. The latter parts are secured tothesidebarsofithetruckfrom Specification of Letters Patent.

which the load is transmitted in any desired manner, as by pedestals to the axle boxes 7 and thence through the Wheels 5 to the rails. The latter of the above recited parts are shown in dotted lines only, s they form, in themselves, no part of the present invention,

and a detailed showing thereof would merely i confuse the disclosure.

The bolster which embodies the dominant features of this invention comprises a kingpost 9, to the upper and lower portions of which are secured pairs of anglo members 1() and 11. It may here be noted that the terni angle member, or its equivalent, is used throughout the following claims to denote s member provided with longitudinal flanges or webs angularly disposed with reference one to another. Members 1G and 11 converge in Vertical planes, as best shown by reference to Fig. 4 of the drawings, and terminate at each lateral end of the bolster within end castings 12, the construction of which will hereafter be described in detail.

The lingpost 9 comprises an upper portion 3 and a lower portion l-it connected upon their front and rear edges, with reference to the position of the bolster upon the truck, by webs 1.5 and 16 respectively. The upper and lower portions are also connected by a tubular casing l? adapted to inclosc and guide the lower end of the kingpin which projects dovmwardly through the center plate 18 in the well-known manner. From casing 17, webs 19 and 20 extend respectively laterally and to the front and rear, the latter Webs being connected with webs 15 and 16, as best shown in Fig. 2 of the drawings. The upper and lower portions of the kingpost are rovided` adje-cent their front and rear e ges with de resse-d or offset portions. within which t e horizontal flanges of the angle members rest, tlnis iermitting the snrfeces thereof to lie iiush with the upper and lower surfaces of the post.

The end casting 12, with reference to which it may here be noted that the term casting77 is used in a broad sense as covering any metallic member, irrespestivoV of its method of manufacture, comprises a baseportion 21 extending beneath the lower angle members 11 and flanged at its ends so aslto embrace the same, as best shown at 22 in Fig. 3 of the drawings. The upper portion of the end casting forms a support for the side bearing of the truck and is connected with the base by ai longitudinal web 23 and 'IIC lateral webs J1, the latter being provided with outwardly-disposed Ilanges 35 adapted to rest upon the angle men'lbers ltt Additional stillness is allorded the holster by channel sections 2n disposed at each side olI the hingpost between the angle members lt) and ll and having their llanges riveted thereto, and plates 2T tying the lower 'llanges ol` the angle members l l one to another.

'l`he entire holster, with the exception olI the end castings l! is preferably covered by a plate or sheet 2N perforated V[or the hingpin at 2E) and riveted to the kingpost and angle members l0.

lt will be understood that rivets or other retaining devices are used througlnmt the entire above-tIeseribetl structure wherever nercssary. although, on aceountolI the interlocking disposition oll the several tarts the stress upon these members is reduced to a minimum.

rlhe action ol the above-tlescribed embodiment ol' my invention, which should be in large part obvious l'rom the above description. is as follows: Assuming the load to be applied through the renter plate 18, the same is' transmitted through the angle members 1t) and 1] to the springs the entire de vice acting as a truss in which the liingpost forms a strut or spacing member and the upper and lower chords are formed by the angle members 10 and ll respectively. inasmuch ,as the latter members are fitted within and securely tied to the end castings, and no relative movement due to thrust or pull thereof can take )lace at this point, the bolster can fail only hy buckling of the upper members or tearing out or apart ot the lower chord, as above deiined. The chance of buckling is substantially eliniinated not only by the ilanged conformation ot' the angle members, but by the auxiliary stiii'ening devices 2G and the plate 2S. The lower members, moreover, on account of their connection not only with the kingpost, the plates 27 and the channel members 26, but by the way in which they are tied into the end castings, cannot under any conditions ol use be torn out of their original position. Thus, as the chance oi the kingpost collapsing is, by reason of the fianged construction, negligible, the bolster will preserve its original form and act as a unit under the most severe conditions of use.

It will thus be seen that I have provided a device which accomplishes the objects of my invention in a most simple and efficient inanner an d which is of inexpensive and light construction and gains its high degree of etliciency by reason of' the careful disposition ol the metal employed, whereby all arts of cach member are used to their full va ue with, of course, the proper factor of safety.

As many cianges could be made in the above construction and many apparently widely different embodiments of my invention could be Iliade without departing from the scope thereol, l intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrativ I and not in a limiting sense. l desire it also to be understood that the language used in the l'ollowing claims is intended to rover all ol the generic and specilic l'eatures oll the invention herein described and all statements olthe scope olI the invention, which. as a matter ol language, lnight he said to i'all therelwtween.
